Community page lists its sub-pages (#14)

## Problem

The `/community` page rendered as an empty stub — just the header, no
body. The default `list.html` layout ranges over child **content**
pages, but the community section has none. Its sub-pages (Learning,
Calendar, Authors, Forums, Discord Archive) only existed in the nav
dropdown via the `community` menu.

## Change

- Add `themes/powershell-community/layouts/community/list.html`, a
section-specific layout that renders the `community` menu entries as a
card grid (keeping the section's intro text and header styling).
- Enrich the `community` menu entries in `hugo.yaml` with `icon` and
`description` params (and `external: true` on Forums so it opens in a
new tab).

Because the page is driven off `.Site.Menus.community`, future sub-pages
only need a menu entry to show up in both the nav dropdown and the page
body — they stay in sync automatically.

## Testing

- `hugo` builds clean (no new warnings).
- Verified the rendered `/community/index.html` contains all five cards
with correct icons and the external Forums link.
